In recent years, people have been exposed to several types of substances with broad spectrum due to the rapidly evolving technology. One of these chemical substance groups are pesticides. Pesticides have been an essential part of agriculture to protect crops and livestock from pest infestations and yield reduction for many decades.

Pesticides, Environmental Pollution, and Health

The impact of pesticides consists of the effects of pesticides on non-target species. Pesticides are chemical preparations used to kill fungal or animal pests. Other problems emerge from poor production, transport and storage practices. Each pesticide or pesticide class comes with a specific set of environmental concerns. The arrival of humans in an area, to live or to conduct agriculture, necessarily has environmental impacts.

Toxicology: Agriculture And Environment: Pesticide Chemistry And Toxicology

This chapter provides an overview of ethical issues related to the development of industrial chemicals. While they do contribute to advancements in agriculture, medicine, transportation, hygiene, and human leisure, these chemicals can concomitantly pose serious threats to human and environmental health. The chapter examines the public health cost-benefit of environmental chemicals and the regulatory frameworks for human health protection in various countries, focusing on evidence-based decision-making, risk analysis, a precautionary approach, and international consensus. Specific ethical concerns discussed relate to the impacts and lasting effects of pesticides, the influence of economic stability and profit derived from industrial chemicals, conflicts between public health priorities and environmental protections, and inequities and injustices in the distribution of risks and burdens associated with industrial chemicals. Keywords: industrial chemicals , pesticides , public health , environmental health , risk analysis , precautionary principle , post-anthropocentric ethics , inequities , public health ethics. Chemical development and material science have revolutionized agriculture, medicine, commerce, transportation, hygiene, and nearly every other aspect of human life. They have advanced research and innovation, contributed to economic growth, and allowed longer high-quality lives for many individuals.

Pesticides can be grouped according to the types of pests which they kill: Insecticides - insects Herbicides - plants Rodenticides - rodents rats and mice Bactericides - bacteria Fungicides - fungi Larvicides - larvae Fig. For example, they can be grouped according to the chemicals in them or to the method of application. Insecticides kill insects by getting inside their bodies where they then act as poison. There are three different ways insecticides can get into an insect body. In insects, the skin is called the cuticle.

The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. Among these, organochlorine OC insecticides, used successfully in controlling a number of diseases, such as malaria and typhus, were banned or restricted after the s in most of the technologically advanced countries. The introduction of other synthetic insecticides — organophosphate OP insecticides in the s, carbamates in s and pyrethroids in s and the introduction of herbicides and fungicides in the s—s contributed greatly to pest control and agricultural output. Ideally a pesticide must be lethal to the targeted pests, but not to non-target species, including man. Unfortunately, this is not the case, so the controversy of use and abuse of pesticides has surfaced.

February 1, The impacts of pesticides on wildlife are extensive, and expose animals in urban, suburban, and rural areas to unnecessary risks. Beyond Pesticides defines "wildlife" as any organism that is not domesticated or used in a lab. This includes, but is not limited to, bees, birds, small mammals, fish, other aquatic organisms, and the biota within soil. Wildlife can be impacted by pesticides through their direct or indirect application, such as pesticide drift, secondary poisoning, runoff into local water bodies, or groundwater contamination. It is possible that some animals could be sprayed directly; others consume plants or prey that have been exposed to pesticides. Pesticide exposure can be linked to cancer, endocrine disruption, reproductive effects, neurotoxicity, kidney and liver damage, birth defects, and developmental changes in a wide range of species.

Если Меган продала кольцо и улетела, нет никакой возможности узнать, где оно. Беккер закрыл глаза и попытался сосредоточиться. Итак, каков следующий шаг. Он решил подумать об этом через минуту. Сейчас ему надо было совершить давно уже откладываемую прогулку в туалетную комнату. ГЛАВА 64 Сьюзан осталась одна в тишине и сумерках Третьего узла. Стоявшая перед ней задача была проста: войти в компьютер Хейла, найти ключ и уничтожить все следы его переписки с Танкадо.

Танкадо приближается справа, Халохот - между деревьев слева. - У нас почти не осталось времени, - сказал Фонтейн.  - Давайте ближе к сути дела. Агент Колиандер нажал несколько кнопок, и кадры стали сменяться быстрее. Люди на подиуме с нетерпением ждали, когда на экране появится их бывший сослуживец Энсей Танкадо.

Он отпустил ее и прижал ладони к лицу. Из носа у него пошла кровь. Хейл упал на колени, не опуская рук. - Ах ты, мерзавка! - крикнул он, скорчившись от боли. Сьюзан бросилась к двери, моля Бога, чтобы Стратмор в этот миг включил резервное энергоснабжение и дверь открылась.

Пестрое сборище пьяных и накачавшихся наркотиками молодых людей разразилось истерическим хохотом. Двухцветный встал и с презрением посмотрел на Беккера.

 Д-директор. Все повернулись к экрану. Это был агент Колиандер из Севильи.

Стратмор бросил взгляд на лежавшего в беспамятстве Хейла, положил беретту на столик рядом со Сьюзан и крикнул, перекрывая вой сирены: - Я сейчас вернусь! - Исчезая через разбитое стекло стены Третьего узла, он громко повторил: - Найди ключ. Поиски ключа не дали никаких результатов. Сьюзан надеялась, что Стратмору не придется долго возиться с отключением ТРАНСТЕКСТА. Шум и мелькающие огни в шифровалке делали ее похожей на стартовую площадку ракеты. Хейл зашевелился и в ответ на каждое завывание сирены начал моргать.

    Pesticides benefit the crops; however, they also impose a serious negative impact on the environment. Excessive use of pesticides may lead to the destruction of biodiversity. Pollution as a result to overuse of pesticides and the long term impact of pesticides on the environment are also discussed in the chapter.

    Countless chemicals are environmentally stable, prone to bioaccumulation, and toxic [6]. Because some pesticides can persist in the environment.
