Pollution has negative implications in the surrounding environment.

An estuary is an intermediate passageway of water between the mouth of a river and a sea coast. This passageway is comprised of a river mouth channel reach with river inflow (fresh water) from upstream and outflow discharge on the downstream side into a constantly changing tailwater level of sea water (salt water). Estuaries are continuously affected by tidal fluctuations and are among the most complex bodies of water encountered in water pollution control. The dominant features of an estuary are variable salinity, a salt wedge or interface between salt and fresh water, and often large areas of shallow, turbid water overlying mud flats and salt marshes. Nutrients are largely supplied to an estuary from the inflowing river and combine with the sea water habitat to provide prolific production of biota and sea life. Especially desired are seafoods harvested from estuaries.

Pollution takes place when pollutants contaminate the natural environments.

The degree to which mandatory plans are prescriptive also varies - for example, in regard to penalties and sanctions. Few authorities have the power to require specific changes in the content of pollution prevention plans; almost all have the power to require changes in the plan in the event that the formal requirements have not been met - for example, if some plan headings have not been addressed. There are virtually no examples of penalties or sanctions in the event that the substantive requirements of a plan have not been met. In other words, legal requirements for pollution prevention planning are far from traditional.

Another main pollutant in this environment is the SPM.

Nearly 35 percent of India total land area is subjected to serious environmental pollution.

There are several reasons for this. The first is that pollution prevention is a new discipline in the context of a general, traditional failure to see environmental protection as a function of processes utilized and adopted within workplaces. A second reason is that worker-management co-determination in the area of environmental protection is not well advanced. Workers in many countries have legal rights, for instance, to joint workplace health and safety committees; to refuse unsafe or unhealthy work; to health and safety information; and to training in health and safety issues and procedures. But there are few legal rights in the parallel and often overlapping area of environmental protection, such as the right to joint union-management environment committees; the right of employees to “blow the whistle” (go public) on an employer’s anti-environmental practices; the right to refuse to pollute or to degrade the outside environment; the right to environmental information; and the right to participate in workplace environmental audits (see below).

In 1989, Environment Canada consolidated and streamlined its legal mandates into a single statute. CEPA provides the federal government with comprehensive powers (e.g., information gathering, regulations making, enforcement) over the entire life cycle of chemicals. Under CEPA, the New Substances Notification Regulations establish screening procedures for new chemicals so that persistent toxics that cannot be adequately controlled will be prohibited from being imported, manufactured or used in Canada. The first phase of the Priority Substances List (PSL I) assessment programme was completed in 1994; 25 of the 44 substances assessed were found to be toxic under the definition of CEPA, and the development of management strategies for these toxic chemicals was initiated under a Strategic Options Process (SOP); an additional 56 priority substances will be nominated and assessed in phase II of the PSL programme by the year 2000. The National Pollutant Release Inventory (NPRI) was implemented in 1994 to mandate industrial and other facilities that meet the reporting criteria to annually report their releases to air, water and land, and their transfers in waste, of 178 specified substances. The inventory, modelled on the Toxic Release Inventory (TRI) in the United States, provides an important database for prioritizing pollution prevention and abatement programmes.

To reaffirm their commitment to the virtual elimination goal for persistent toxic substances, Canada and the United States amended the 1978 Agreement through a protocol in November 1987 (United States and Canada 1987). The protocol designated areas of concern where beneficial uses have been impaired around the Great Lakes, and required the development and implementation of remedial action plans (RAPs) for both point and non-point sources in the designated areas. The protocol also stipulated lakewide management plans (LAMPs) to be used as the main framework for resolving whole-lake impairment of beneficial uses and for coordinating control of persistent toxic substances impacting each of the Great Lakes. Furthermore, the protocol included new annexes for establishing programmes and measures for airborne sources, contaminated sediments and dump sites, spills and control of exotic species.
