Answer:

Dosage and form in which the chemical is present are the factors that determine the level of harm of chemical on the environment.

Explanation:

Dosage usually mean amount of chemical. Some chemicals cause harm to the environment in a very low amount and some chemicals damage the environment when the amount is too high, these chemicals are not considered as toxic. Form of chemicals also affects its toxicity. Some chemicals are harmful in one state and beneficial in another state.

Answer: Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms.[1][2] Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem levels.

Rachel Carson is considered the mother of environmental toxicology, as she made it a distinct field within toxicology in 1962 with the publication of her book Silent Spring, which covered the effects of uncontrolled pesticide use. Carson's book was based extensively on a series of reports by Lucille Farrier Stickel on the ecological effects of the pesticide DDT.[3]

Organisms can be exposed to various kinds of toxicants at any life cycle stage, some of which are more sensitive than others. Toxicity can also vary with the organism's placement within its food web. Bioaccumulation occurs when an organism stores toxicants in fatty tissues, which may eventually establish a trophic cascade and the biomagnification of specific toxicants. Biodegradation releases carbon dioxide and water as by-products into the environment. This process is typically limited in areas affected by environmental toxicants.

Harmful effects of such chemical and biological agents as toxicants from pollutants, insecticides, pesticides, and fertilizers can affect an organism and its community by reducing its species diversity and abundance. Such changes in population dynamics affect the ecosystem by reducing its productivity and stability.

Although legislation implemented since the early 1970s had intended to minimize harmful effects of environmental toxicants upon all species, McCarty (2013[4]) has warned that "longstanding limitations in the implementation of the simple conceptual model that is the basis of current aquatic toxicity testing protocols" may lead to an impending environmental toxicology "dark age".

Consider how sedimentary rocks are formed, from sediments! Sediments are composed of particles that often come from existing

How do fossils of limb structures provide evidence that ancient and modern tetrapods are related

It suggests to how modern and ancient tetrapods have the ancestry which come from early tetrapods.
