  2. Soil contamination - Wikipedia

    en.wikipedia.org/wiki/Soil_contamination

    A study investigating the heavy metal pollution in the vicinity of the smelter reveals that elevated levels of nickel and copper were found in the soil; values going as high as 5,104ppm Ni, and 2,892 ppm Cu within a 1.1 km range of the smelter location. Other metals were also found in the soil; such metals include iron, cobalt, and silver.

  3. Environmental radioactivity - Wikipedia

    en.wikipedia.org/wiki/Environmental_radioactivity

    The distribution coefficient K d is the ratio of the soil's radioactivity (Bq g −1) to that of the soil water (Bq ml −1). If the radioactivity is tightly bonded to by the minerals in the soil then less radioactivity can be absorbed by crops and grass growing in the soil. Cs-137 K d = 1000; Pu-239 K d = 10000 to 100000; Sr-90 K d = 80 to 150 ...

    Overview of the interdisciplinarity of environmental toxicology Categories of organisms commonly used for assessing environmental toxicity. 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.

  6. Cobalt poisoning - Wikipedia

    en.wikipedia.org/wiki/Cobalt_poisoning

    Cobalt poisoning is intoxication caused by excessive levels of cobalt in the body. Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12 . A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia .

  7. Dutch pollutant standards - Wikipedia

    en.wikipedia.org/wiki/Dutch_pollutant_standards

    The soil remediation intervention values indicate when the functional properties of the soil for humans, plants and animals is seriously impaired or threatened. They are representative of the level of contamination above which a serious case of soil contamination is deemed to exist.

    A legal team suing the troubled New-Indy paper mill in South Carolina says it has uncovered evidence that dioxin, a cancer-causing material, is seeping into the Catawba River from the more than 60 ...

  9. Agricultural pollution - Wikipedia

    en.wikipedia.org/wiki/Agricultural_pollution

    Conservation agriculture relies on principles of minimal soil disturbance, the use of mulch and/or cover crops as soil cover, and crop species diversification. [47] It enables the reduction of fertilizers, which in turn reduces ammonia emissions and greenhouse gas emissions.
