Contamination Caused by Pesticides in Our Environment

The first chemical to be discussed is Agent Orange; Agent Orange has been identified as a human carcinogen; this chemical was introduced during the Vietnam War as a defoliant for the thick Vietnamese jungle. Although Agent Orange contained a variety of herbicides, most of the pesticide contained Phenoxyacetic acid – based herbicide 2,4-D and 2,4, 5-T. The most common mixture

Pesticides and their alternatives are an undeniable part of modern life, used to protect everything from flower gardens to agricultural crops from specific pests (Saravi & Shokrzadeh, 2011) Pesticides are considered a vital component of modern farming, playing a major role in maintaining high agricultural productivity. Consequently, in high-input intensive agricultural production systems, the widespread use of pesticides to manage pests has emerged as a dominant feature (Saravi & Shokrzadeh, 2011) Pesticides comprise a large number of substances that belong to many different chemical classes, they are applied to crops at various stages of cultivation to provide protection against pests and during post-harvest storage to preserve quality, to ensure the safety of food for consumers and regulate international trade and legislation. Pesticides are considered to be essential for agricultural development; some of them can cause serious ambient contamination, principally in food (Sitta et al., 2000; Gonzalez et al., 2003). This hazard, could be further increased in case of vegetable fruits which are usually consumed freshly e.g. consumed vegetable fruits freshly contaminated with pesticide residues, more than allowable tolerance (Romeh et al., 2000). Various human health related

It has been a prime location for studies to be conducted by health organizations to see if there are any links to the pesticide usage occurring along with people living in the vicinity of where it is being used. ARTICLE PESTICDES STUDY (Kehoe) The study correlates a link between certain chemicals that are used in the manufacturing of pesticides and these chemical ORGANOCHLORINES to Alzheimer’s disease along with many autism related defects between children. Children are who we try to keep safe as they are the young and will be our future. Pregnant women living in pesticide applied areas were more likely to have a child with birth defects as the chemicals are absorbed through the air and can reach the fetus via the bloodstream. These are also the most susceptible to these chemicals being used by farmers and the by the produce they

Pesticides are also found in the Great Lakes. These pesticides are made up of dangerous chemicals like toxaphene and chlordane. The rain transports the pesticides from crops to bodies of water like the Great Lakes. They are then absorbed by phytoplankton and it moves up the food chain from there. Pesticides

What exactly is a pesticide? “A pesticide is a chemical used to prevent, destroy, or repel pests” (EPA). There are many different pests. Some examples are the termites that cause damage to our homes, dandelions in our yards, and

It is the role of EPA to determine that any cancer-causing pesticide or chemical may perhaps not be used despite of its health hazards. If a pesticides social, economic and environmental benefits are believed to have greater relevancies than risks, then there is a need to make food, air, water, and soils free from any form of toxic chemicals (EPA History 2017). Organically mature foods as well as sustainable pest control methods are very key issues to health environment and

This paper argues that there needs to be a greater harmonization of legislation regulating highly hazardous pesticides used in agriculture within all nations. With the numerous studies conducted illustrating the harmful effects to human health and environment, this stricter control of legislation across developed and developing countries is of utmost importance. This requires each nation to have a complete understanding of the methods and practices used to regulate pesticides in other countries and work together to converge the various approaches. It is the role of the government to find a responsible balance between enabling judicious pesticide use where such use is necessary to achieve desirable crop production levels, and reducing the

The initiative tried to discuss the potential environmental and social issues associated with pesticides. Although their website does not clearly state specific examples of this problem, the general organisation attempts to improve ecosystem biodiversity. This initiative as helped to improve this non-governmental organisation’s trustworthiness among the general forestry market because of their tick system. Compared to the other projects (Change Our Fibreboards, FSC Fridays) introduced by FSC, this initiative was more potent because of the rigorous guidelines provided to examine the environmental issues. Some of the strategies show some strengths about the initiative; the 3R and IPM mentioned to prevent any harm

Endocrine Disruptors are chemicals that mimic the hormones or blocks cellular responses in the body. They are known to be present in plastic bottles, food additives, and pesticides (Young, 2010). Some examples of endocrine disruptors are BP-A (Smith, 2008). These chemicals at certain dose, can interfere with the endocrine (or hormone) system in mammals. These disruptions can cause cancerous tumors, birth defects, and other developmental disorders. This paper will describe the different forms of endocrine disruptors in the environment

The question lies does environmental contamination have a major effect on real estate properties? Well environmental contamination turns out can cost the owner of the property or a potential buyer. Environmental contamination on a property may have some implication on the on the property value. Not only could potentially hurt the owner or potential buyer financially it could also do physical damage to the property as well.

The contamination it is a global problem is the environmental damage caused by substances or objects with carbon dioxide, which is caused mainly by the industry either through contaminated water burning garbage or gases released directly from factories. An example of this is the production of nuclear energy, because the plants release the gas produced during the process so that it does not raise pressure and can explode, causing damage to the ozone layer, but this also causes the air to become contaminated and less able to breathe. These 2 things can cause diseases like lung cancer, skin cancer and asthma among others, and most diseases caused by this reason can become deadly if they are not treated on time or detected too

Pesticides cause biochemical changes in fish and influence their activities changes enzyme activity in the exposure phase and recovery phase. This change is due to the induced biotransformation to meet the increased energy demands under sustained and prolonged toxic stress as an adaptive response. Changes in the levels of oxidative enzymes in the gill and muscle tissues of the pesticide exposed fish suggested that it is due to the toxic effect of the combination pesticide (Chlorpyrifos 50% + Cypermethrin 5% EC). Pyrethroid are metabolized and eliminated significantly more slowly by fish than by mammals or birds (Bradbury & Coats 1989). Oxidative stress occurs when critical balance between oxidants and antioxidants is disrupted due to excessive
