The Major Environmental Problems Related to Pollution

The Major Environmental Problems Related to Pollution
Pollution, also called environmental pollution, is the addition of any substance solid, liquid, or gas or any form of energy such as heat, sound, or radioactivity into the environment at a rapid rate of diffusion, dilution, decomposed, recycled, or stored in a harmless form. Pollution can take many forms the air we breathe, the water we drink, the soil we use to grow our food, the sparkling skies and even the noises we hear every day. , they can all contribute to health problems and may lead to low quality of life. Environmental pollution is one of the most serious global challenges. Wild type organisms have a slow degradation rate of hazardous substances. Currently, advanced molecular biology tools along with conventional approaches allow us to rapidly degrade or deposit hazardous materials from the atmosphere. In a developing country like India, the use of environmental standards as a decision making criterion should be properly evaluated. If the norms of developed countries apply in India, the cost would be much higher. Thus, the selected parameters should be suited to the economic condition of the country. Pseudomonas fluorescens and Haemophiluspa that were found in petrochemical waste disposal sites contaminated with phenanthrene, anthracene, fluorine, pyrene, and asenaphthene showed a 70 -100 drop in PAHs over 40 days.

A Report on Animal Behaviour Ethology

October 09, 2021 0
A Report on Animal Behaviour Ethology
Ethology is the scientific study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait. Behaviourism as a term also describes the scientific and objective study of animal behaviour, usually referring to measured responses to stimuli or to trained behavioural responses in a laboratory context, without a particular emphasis on evolutionary adaptivity. Throughout history, different naturalists have studied aspects of animal behaviour. Ethology has its scientific roots in the work of Charles Darwin 1809-1882 and of American and German ornithologists of the late 19th and early 20th century, including Charles O. Whitman, Oskar Heinroth 1871-1945 , and Wallace Craig. The modern discipline of ethology is generally considered to have begun during the 1930s with the work of Dutch biologist Nikolaas Tinbergen 1907-1988 and of Austrian biologists Konrad Lorenz and Karl von Frisch 1886-1982 , the three recipients of the 1973 Nobel Prize in Physiology or Medicine. Ethology combines laboratory and field science, with a strong relation to some other disciplines such as neuroanatomy, ecology, and evolutionary biology. Ethologists typically show interest in a behavioural process rather than in a particular animal group, and often study one type of behaviour, such as aggression, in a number of unrelated species.Ethology is a rapidly growing field. Since the dawn of the 21st century researchers have re examined and reached new conclusions in many aspects of animal communication, emotions, culture, learning and sexuality that the scientific community long thought it understood. New fields, such as neuroethology, have developed.Understanding ethology or animal behaviour can be important in animal training. Considering the natural behaviours of different species or breeds enables trainers to select the individuals best suited to perform the required task. It also enables trainers to encourage the performance of naturally occurring behaviours and the discontinuance of undesirable behaviours.

Prevention of Type 2 Diabetes Mallitus A Focus on Physical Activity and Lifestyle Changes

Diabetes is a costly disease affecting 387 million individuals globally and 28 million in the United States. Its precursor, prediabetes, affects 316 and 86 million individuals globally and in the United States, respectively. People living with elevated blood glucose levels are at high risk for all cause mortality and numerous cardiometabolic ailments. Fortunately, diabetes can be prevented or delayed by maintaining a healthy lifestyle and a healthy body weight. In this review, we summarize the literature around lifestyle diabetes prevention programs and provide recommendations for introducing prevention strategies in clinical practice. Overall, evidence supports the efficacy and effectiveness of lifestyle diabetes prevention interventions across clinical and community settings, delivery formats eg, individual , group , or technology based , and implementers eg, clinicians, community members . Evidence based diabetes prevention strategies that can be implemented in clinical practice include brief behavior change counseling, group based education, community referrals, and health information technologies. These strategies represent opportunities where practitioners, communities, and health care systems can work together to provide individuals with education, support and opportunities to maintain healthy, diabetes free lifestyles. The worldwide prevalence of type 2 diabetes mellitus is increasing at a rapid rate, predominantly because of changes in environmental factors interacting with individual genetic susceptibility to the disease. Data from 20 longitudinal cohort studies present a consistent picture indicating that regular physical activity substantially reduces risk of type 2 diabetes. Adjustment for differences in body mass index between active and inactive groups attenuates the magnitude of risk reduction, but even after adjustment, a high level of physical activity is associated with a 20 30 reduction in diabetes risk.It is possible to prevent type 2 diabetes. Whether you have several of the risk factors or you’ve been told you have prediabetes, you can take action and reduce your risk of developing diabetes. Being overweight BMI greater than 25 kg m2 increases your risk of developing type 2 diabetes, so if you’re overweight, you should take steps to lose weight. By losing 5 to 10 of your body weight, you can reduce your risk. You can do this by eating smaller portions and being more physically active, which, conveniently enough, are two other ways to prevent type 2 diabetes. First, build your meals around vegetables rather than meat, and cut back on your starches. Avoiding added sugar and sugar substitutes, as well as processed grains. Instead, substitute with heart healthy fats, high protein whole grains eg, pasta made from chickpea flour, quinoa, sprouted wheat bread , fruit to add sweetness even to salads or as a snack, and lean meats and dairy products. Seek out new, appetizing recipes there are many cookbooks that offer lower fat and healthier recipes. Aim for some daily physical activity. Exercise is important to help prevent type 2 diabetes and has so many other benefits. It can help you keep lost weight off, and improve your heart health, and if you’re insulin resistant, it can help increase your bodys response to insulin exercise so you will have better blood glucose control. Drinking water throughout the day is always good to keep your organs and skin healthy. Of course, getting some fluid before, during and after exercise is just as important to avoid becoming dehydrated.

Impact of Lead Toxicity on Body Defense

June 17, 2021 0
Impact of Lead Toxicity on Body Defense

Lead is regarded as a potent occupational toxin and its toxicological manifestations are well known. The non biodegradable nature of lead is the prime reason for its prolonged persistence in the environment. Human exposure to lead occurs through various sources like leaded gasoline, industrial processes such as lead smelting and coal combustion, lead based paints, lead containing pipes or lead based solder in water supply systems, battery recycling, grids and bearings, etc. Although lead toxicity is a highly explored and comprehensively published topic, complete control and prevention over lead exposure is still far from being achieved. There is no such level of lead that appears to be necessary or beneficial to the body and no “safe” level of exposure to lead has been found. Lead toxicity is a particularly insidious hazard with the potential of causing irreversible health effects. It is known to interfere with a number of body functions and it is primarily affecting the central nervous, hematopoietic, hepatic and renal system producing serious disorders. Acute toxicity is related to occupational exposure and is quite uncommon. Chronic toxicity on the other hand is much more common and occurs at blood lead levels of about 40–60 ug dL. It can be much more severe if not treated in time and is characterized by persistent vomiting, encephalopathy, lethargy, delirium, convulsions and coma. Young children are particularly vulnerable to the toxic effects of lead and can suffer profound and permanent adverse health effects, particularly affecting the development of the brain and nervous system. Lead also causes long term harm in adults, including increased risk of high blood pressure and kidney damage. Exposure of pregnant women to high levels of lead can cause miscarriage, stillbirth, premature birth and low birth weight. Young children are particularly vulnerable to lead poisoning because they absorb 4–5 times as much ingested lead as adults from a given source. Moreover, children’s innate curiosity and their age appropriate hand to mouth behaviour result in their mouthing and swallowing lead containing or lead coated objects, such as contaminated soil or dust and flakes from decaying lead containing paint. This route of exposure is magnified in children with a psychological disorder called pica persistent and compulsive cravings to eat non food items , who may, for example pick away at, and eat, leaded paint from walls, door frames and furniture. Exposure to lead contaminated soil and dust resulting from battery recycling and mining has caused mass lead poisoning and multiple deaths in young children in Nigeria, Senegal and other countries. Once lead enters the body, it is distributed to organs such as the brain, kidneys, liver and bones. The body stores lead in the teeth and bones where it accumulates over time. Lead stored in bone may be remobilized into the blood during pregnancy, thus exposing the fetus. Undernourished children are more susceptible to lead because their bodies absorb more lead if other nutrients, such as calcium or iron, are lacking. Children at highest risk are the very young including the developing fetus and the economically disadvantaged. Lead poisoning occurs when lead builds up in the body, often over a period of months or years. Research indicates about 500,000 U.S. children between the ages of 1 and 5 have blood lead levels above 5 micrograms per deciliter, the reference level at which the CDC recommends public health actions be initiated. Children under the age of 6 are especially vulnerable because their growing bodies absorb more lead than adults and because they tend to put their hands or other objects, which may be contaminated with lead dust, into their mouths. The signs and symptoms of lead poisoning often dont appear until dangerous amounts of lead have accumulated. Even low levels of lead in blood have been shown to affect IQ, the ability to pay attention and academic achievement. At very high levels, lead poisoning can be fatal. The effects of lead exposure cannot be corrected. Lead pollution can also cause irreversible encephalopathy, seizure, coma and even death. Fatigue, memory loss, high blood pressure, nephropathy, gastrointestinal disturbances, weight loss and immuno suppression are other common toxic effects of lead exposure in animals. Prenatal exposure to metal may also cause birth defects, miscarriage and underdeveloped babies.

Entomological Characterisation of Some of the Butterfly Species of Papilionidae from Bastar Division of Chhattisgarh, India

One of the most diversed groups of animals, found abundantly, in all types of environment throughout the world is the ‘Butterflies’. The study and watching of butterflies perhaps is the second interesting pastime for naturalists, next only to ornithology. They belong to the order ‘Lepidoptera, of the phylum ‘Arthropoda’. Amongst more than 100 species found in the Bastar division of Chhattisgarh, due to the rich flora and fauna of the region, some of the most common ones belong to the family Papilionidae. The present article reviews the entomological characterisation of the five common species of Papilionidae butterflies from Bastar division of Chhattisgarh, India.

Effects of Incorporated Green Manure and Inorganic Fertilizer on Amaranth Amaranthus Caudatus. L Vegetable

Four cowpea varieties Oloyin, Drum, Zobo and White Mallam , and four levels of nitrogen fertilizer 20, 40, 60 and 80 kg N ha were applied at 2 weeks after planting WAP to the vegetable Amaranth between October 2018 to April 2019. The cowpea green manure was incorporated into soil 6 WAP and left for a week to decompose before planting the vegetable Amaranth. Growth of cowpea varieties used as green manure in 2018 showed no significant difference. However, in 2019 the canopy height and fresh weight at 3 WAP were significantly p 0.05 different among cowpea varieties. The canopy height of Oloyin, Drum and White Mallam were similar but significantly p 0.05 higher than that of Zobo variety. Similarly, application of 60 and 80 kg N ha significantly produced more yield relative to 0 and 40 kg N ha of inorganic fertilizer rates. Generally, higher significant yield p 0.05 was recorded in the second cycle of planting. This study concluded that green manure from Oloyin produced yield of Amaranth us 11.0 47.3 t ha which was similar to the yield obtained from 80 kg N ha 12.13 37.7t ha.

Succession of Arthropods on White Rat Carcasses in Ile Ife, Southwestern Nigeria

September 05, 2020 0
Succession of Arthropods on White Rat Carcasses in Ile Ife, Southwestern Nigeria

The forensic information provided by decomposition of small carcasses often goes unnoticed, even in advanced economies, due to frequent neglect. This paper reports the succession pattern of arthropod species that associated with carcasses of white rat, Rattus norvegicus Berkenhout Rodentia Muridae , in Ile Ife, southwestern Nigeria. Four bushy sites were chosen for the study and nine rat carcasses were placed at each site once a season for two seasons. The carcasses were monitored daily until the process of decay was over. The visiting and colonizing invertebrates were collected daily and identified. Immatures were also collected and reared in the laboratory till adult emergence for easy identification. The carcasses went through five stages of decay and the arthropods arrived in the order Diptera early fresh stage , Hymenoptera late fresh stage , Coleoptera and Dermaptera active decay stage , and Araneae and Oribatida advanced decay stage . Dipteran flies were the first arthropods to interact with the remains but ants were the only arthropods that associated with all the five stages of decay. A total of 9828 arthropods 4415 adults and 5413 immatures belonging to six orders in two classes of the phylum were collected in the study. The proportion of faunal abundance was Diptera 75.10 , Hymenoptera 22.90 , Coleoptera 1.80 , Dermaptera 0.10 , Oribatida 0.08 and Araneae 0.02 . Rate of decay was faster and faunal population was higher on carcasses during the dry season compared to the wet. Faunal population was also higher on carcasses placed in close proximity to the Zoological garden. The implications of these results on accuracy of estimated postmortem interval PMI and applicability in law were discussed.

Cardiovascular Diseases Major Mortality Factor in Modern Era

Cardiovascular diseases CVD is the disease of heart and blood vessels which include mainly coronary artery disease CAD , angina pectoris and myocardial infarction Heart attack . CVD also include stroke, heart failure, hypertensive heart diseases, rheumatic heart disease, cardiomyopathy, abnormal heart rhythms, congenital heart disease, valvular heart diseases, carditis, arotic aneursysms, peripheral artery disease, thromboembolic disease, venous thrombosis. But most of the people die due to coronary artery diseases which is due to Atherosclerosis caused by the accumulation of fat in the inner wall of the large and intermediate artery called atheromatous so it prevent from blood flow that leads to blockage. Today it is biggest reason of increase the mortality rate of people worldwide. Some important factor responsible for CVD are Physical inactivity, Food habit, Alcohol consumption and smoking. All these factors cause high level of plasma triglycerides, low level of HDL high density lipoprotein and LDL low density lipoprotein , higher amount of cholesterol deposition in artery. Deposition of cholesterol in artery causes endothelial dysfunction, myocardial infraction, alters insulin sensitivity, blood lipid and lipoprotein profile, body composition, systemic inflammation, increase blood pressure, decreases functional capacity of heart, weakening of the heart muscles which lead to cardiomyopathy and sudden heart failure.

Impact of Imidacloprid 17.8 SI on Biochemical Parameters of the Fresh Water Fish Catla Catla

Use of pesticide in integrated farming in paddy field is recognized as a potential threat in aquatic organisms. The effect of sublethal toxicity of imidacloprid 17.8 SL pesticide on some biochemical parameters of a freshwater fish Catla catla were studied after 24 hr, 48 hr, 72 hr and 96 hr of exposure. The lethal concentration LC50 of imidacloprid 17.8 SL for 96 hr was 4.11 ppm. The study suggests that exposure to imidacloprid 17.8 SL at low concentration results in significant biochemical alterations. The biochemical response of C. catla to the exposure to sub lethal concentrations of imidacloprid 17.8 SL showed a significant decrease p 0.001 of proteins and glycogen in muscle and liver tissues compared to the control group. The observations from the present study showed that, imidacloprid 17.8 SL altered the biochemical composition of the various organs of test fish, due to utilization of biochemical energy to counteract the toxic stress.

Impact of Silicon Dioxide Nanoparticle on Fresh Water Fish Clarius Batrachus
Clarias batrachus, a freshwater Indian air breathing catfish is one of the important fish species. It is treated as a typical example to deal with the alimentary canal of a teleost and a test animal in many laboratories of Indian Universities . However, the effect of silicon dioxide nanoparticles on Indian Air breathing fishes is lacking. Therefore, the present work was designed to evaluate the median lethal dose of silicon dioxide nanoparticles on Clarias batrachus. The work will help in deciding the toxicity level of silicon dioxide nanoparticles for the higher yield of this fish. Nanotechnology an advanced tool to synthesis atomic level particles. Increased application of silicon dioxide nanoparticles results in the bioaccumulation of these particles in the environment. The fate and effect of nanomaterials in the environment has raised concern about their environmental risk to aquatic organisms. Silica nanoparticles SiO2 NPs find its uses in various fields and are inevitably released into the environment. However, the ecotoxicological effects of SiO2 NPs on the freshwater fish remain poorly understood.

Magical Relationship between Love and Biology

Love is a very pleasant feeling that everyone wants. It is also very pleasant to feel in love with someone. Many times it happens to us that we suddenly see someone and our heart beating fast and have a pleasant feeling and people say he is falling in love. Most people consider it as a normal process or as a normal phenomenon. But this normal phenomenon is actually due to sudden chemical changes in our body. However the story of love is not limited to such a small incident. According to scientists and researchers, love has three parts, attraction, attachment and lust. In these three processes our body goes through many changes. These changes are brought about by hormones, pheromones, neurotransmitters, gain etc. Dopamine, serotonin, oxytocin, vasopressin, sex hormones and many more chemicals play a role in the whole process of love. Where oxytocin, in female is responsible for falling deeply in love, while vasopressin in male induces attachment to a particular female. Pheromone affects sexual attraction in a number of ways including through human biology and the menstrual cycle.
