CHEMICAL POLLUTION

- When rain or snow moves on the ground and absorbs pollutants while moving to the water area

• 20 most abundant groundwater compounds in industrial waste disposal sites such as TCE, benzene, vinyl chloride are carcinogenic and affect the liver, brain and nervous system.

• Carbon dioxide is an excellent sensor for sunlight but partially limits the infrared radiation returning from space to the Earth, thus creating a so-called greenhouse effect that prevents rapid cooling of the Earth at night.

• Increasing the amount of carbon dioxide in the atmosphere increases this effect and it is expected to cause global warming.

• Sulfur dioxide, nitrogen oxides, ozone, nitric acid peroxide (PAN) cause photochemical smog and irritate the eyes and lungs.

• Exposure of leaves and needles to contaminants in the air for a prolonged period will damage the waxy coating and help prevent excessive moisture loss and damage from disease, pests, drought and frost.

• Large quantities of chemicals or other substances contaminate the soil system and reduce fertility

• Metallic contaminants - Weave, Pb, Cu, Zn, Hg, Cd, CN, Acid, Alkali etc are released in textile, dye, soap, detergent, medicine, cement, rubber, paper and metal industries.

• Pesticides - fertilizers, insecticides, insecticides, herbicides, rodenticides, fumigants release toxic chemicals such as lead, arsenic, cadmium, mercury and cobalt.

• disturb ecological balance by accidentally or deliberately bringing foreign organisms, animals or plant species into the environment

• Radioactivity - Characteristics of spontaneous emission of alpha, beta and gamma rays by elements such as Ra, Th and U

• Nuclear explosion and nuclear weapons explosion - U - 235, Pu - 239 for nuclear fission, H & Li for fusion. Ballistics includes Sr-90, Cs-137 and I-131

• The influence will vary depending on the radioactivity level of the organism and the nuclear isotope. Radiation destroys human cells and causes cancer

• Long-term exposure to radiation may destroy DNA cells, leading to cancer, progeny genetic defects, and even death.

• Species affecting animals preferentially accumulate specific radioactive material - Oyster deposits Zn - 65, fish Fe - 55, marine animal Sr - 90

• These reagents can be liquid, gas, or solid. Liquid formulations are usually designed to evaporate quickly; this liquid is said to be volatile or has a high vapor pressure

• In July 1917, Germans used mustard gas. Mustard gas easily permeates leather or cloth, causing painful burns on the skin

• Chemical weapons are classified as fatal and ineffective classes. If nausea, visual impairment, etc. cause a failure of less than 1 in 1 lethal dose, the substance is classified as disabled.

• The most commonly used chemicals are four breathing poisons, chlorine, chloropicrin, phosgene, trichloromethyl chloroformate, and skin blowing agent or bis (2-chloroethyl) sulfide called mustard gas.

Soil contamination is defined as the presence of toxic chemicals in the soil (pollutants or pollutants) in a concentration sufficient to pose a threat to human health and ecosystems. In the case of pollutants naturally present in the soil, even if that level is not enough to cause risk, soil contamination still occurs if the level of pollutants in the soil exceeds the naturally occurring level. Regardless of whether it is contaminated or not, all contamination includes naturally occurring compounds (pollutants). These contaminants include metals, inorganic ions and salts (phosphates, carbonates, sulfates, nitrates etc.) and many organic compounds (lipids, proteins, DNA, fatty acids, hydrocarbons, PAH, alcohols etc) included. These compounds are mainly formed by microbial activity of the soil and decomposition of organisms such as plants and animals.
