Pollution: Causes, Effects and Control is the fourth edition of a best-selling introductory level book dealing with chemical and radioactive pollution in its broadest sense.

The scope of the book ranges from the sources of pollutants and their environmental behaviour, to their effects on human and non-human receptors, to the technologies and strategies available for control.5/5(1).

Presents a comprehensive introduction to the nature of pollution, its impact on the environment, and the practical options and regulatory frameworks for pollution control. Sources of pollution, regulatory controls, technological solutions, management and mitigation techniques and assessment tools, are examined in each key area: air, freshwater, and marine pollution, contaminated.

Additionally, radioactive pollution was transported to the marine environment through leaching of contaminated soil. Rain water created run-off which carried the radioactive pollution from the ground to the ocean, adding even more radioactive deposits from the disaster to the sea.

Radioactive contamination of the marine environment and of fisheries products Nature: Radioactive fallout leads to the collection of radioactive materials in the sea and in freshwater environments, whether by direct deposition or by the outflow of such materials.

Marine benthic organisms can be divided into three groups by size: macro- meio- and microbenthos. Generally, in marine ecology, the initial focus of attention when studying sea-bottom ecosystems is given to the macrobenthos.

The macrobenthos comprises 60% of marine species, the meiobenthos 34%, and plankton 6%.Cited by: 8. Environmental impacts of marine pollution- effects, challenges and approaches. Chapter (PDF Available) January with 7, Reads How we measure 'reads'.

Marine pollution is the introduction of substances or energy from humans into the marine environment resulting in such deleterious effects as harm to living resources, hazards to human health, hindrance to marine activities including fishing, impairment of quality for use of seawater, and reduction of amenities.

The first inherent part of pollution is its human origin, i.e., pollution is an anthropogenic process. Pollution: Causes, Effects and Control is the fourth edition of a best-selling introductory level book dealing with chemical and radioactive pollution in its broadest sense.

The scope of the book ranges from the sources of pollutants and their environmental behaviour, to their effects on human and non-human receptors, to the technologies and strategies available for fourth edition.

Radioactive contamination, also called radiological contamination, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids or gases, where their presence is unintended or undesirable.

Such contamination presents a hazard because of the radioactive decay of the contaminants, which produces such harmful effects as ionising radiation and free neutrons. The.

It is estimated that 80 per cent of pollutants in the marine environment originate from land. Some of the hazardous substances, such as toxic heavy metals, persistent organic compounds (including pesticides and industrial chemicals), hydrocarbons and radioactive substances released from industrial, agricultural, municipal and mining activities ultimately enter the marine environment.

Since the beginning, on 21st March, significant radioactive pollution has been observed in the marine environment. This radioactive pollution has three possible origins: liquid radioactive releases from the damaged site, atmospheric fall-out onto the surface of the sea, and transport of radioactive pollution by leaching through contaminated soil.

Recognizing the need to adopt measures for prohibiting all dumping and/or burial of radioactive wastes or other radioactive substances in the sea and/or on the sea-bed and subsoil thereof, Bearing in mind the Convention for the Protection of the Marine Environment and.

Marine pollution due to anthropogenic activities has now become a worldwide environmental concern [].Several researchers [9, 53, 60, W.Q.C., ;] have reported the influence of the indiscriminate discharge of untreated industrial effluent and municipal wastewater on the marine environment in terms of danger to habitats, serious risk to marine life, deterioration of aesthetic values, and Cited by: 1.

In aquatic ecosystems, the main indicators of pollution are contaminated sediments, which are the primary repository of radionuclides and chemical elements in the marine environment.
