Furthermore if the wastewater contains high levels of heavy metals and toxic chemicals Material , these may have to be removed before wastewater disposal. [ WASTEWATER TREATMENT 0 AS 06/05/2015 ]

Take care of hazardous/ toxic substances contained in e-waste Material in an environmentally sound manner while preventing secondary and tertiary emissions. [ EWASTE.UNEP 0 AS MCLH 06/05/2015 ]

Large numbers are already destroyed due to water storage; hydroelectric and irrigation schemes; dams, weirs, and river management works; de-snagging and channelization; changes to flow, water level, and thermal regimes; toxic pollution Material and destruction of nursery and spawning or breeding areas; and use of wetlands for agriculture. [ 2IPCCBIODIVERSITE 0 AS 06/05/2015 ]

On a more local level, uncontrolled discarding or inappropriate waste management/recycling generates significant hazardous emissions, with severe impacts on health and environment. In this context, three levels of toxic emissions Material have to be distinguished: [ EWASTE.UNEP 0 AS 06/05/2015 ]

B100 use could also increase nitrogen oxides emissions, although it greatly reduces other toxic emissions Material . All these issues can be handled, but currently B100 use might be best for professional fleets with maintenance departments prepared to deal with this fuel. [ EERE 0 AS 06/05/2015 ]

Clean Production is a way of designing products and manufacturing processes in harmony with natural ecological cycles. It aims to eliminate toxic wastes Material and inputs and promotes the sustainable use of renewable energy and materials. [ Clean Production Action 0 AS 06/05/2015 ]

Heavy metals and toxic chemicals Material are difficult to remove from sludge. Preventing these chemicals from entering the wastewater or sludge should be the aim of wastewater management for sludge intended for reuse in agriculture or horticulture. [ WASTEWATER TREATMENT 0 AS 06/05/2015 ]

Conversion of sludge, which is heavily contaminated by heavy metals or toxic chemicals Material , to oil is technically feasible (Enersludge process). [ WASTEWATER TREATMENT 0 AS 06/05/2015 ]

Nuclear wastes are neither particularly hazardous nor hard to manage relative to other toxic industrial wastes Material . [ RADIOACTIVE WM 0 AS 06/05/2015 ]

Any toxic compounds (e.g., pesticides) that are in the digester feedstock material Material may become concentrated in the effluent. Therefore, it is important to test the effluent before using it on a large scale. [ EERE 0 AS MCLH 06/05/2015 ]

Warmer climates also increase the risk of food poisoning due to enhanced microbial activity or the occurrence of toxic algae blooms Material in marine environments. [ 5CANADAICC 0 AS 06/05/2015 ]

Some marine-disease organisms and algal species, including those associated with toxic blooms Material , are strongly influenced by one or more of these factors. [ 2IPCCBIODIVERSITE 0 AS 06/05/2015 ]

Since sludge for landfilling usually contains heavy metals or toxic chemicals Material , lining of the landfill with clay or plastic liner may be required to prevent contamination of groundwater. [ WASTEWATER.TREATMENT 0 AS 06/05/2015 ]

Ethanol—an alcohol—is made primarily from the starch in corn grain. It is most commonly used as an additive to petroleum-based fuels to reduce toxic air emissions Material and increase octane. Today, roughly half of the gasoline sold in the United States includes 5%-10% ethanol. [ EERE 0 AS 06/05/2015 ]

Exposure to toxic substances Material , particularly if production facilities become as commonplace as landfill sites or natural gas-fired electricity generating stations. [ RENEWABLE ENERGY SOURCES AND CLIMATE CHANGE MITIGATION 0 AS 06/05/2015 ]

The wind developer must be responsible for any spills of hazardous or toxic materials associated with the wind development, such as gearbox oil, transformer oil, fibreglass, electronics Material , and so on. [ CANWEA 0 AS MCLH 06/05/2015 ]

Using the prioritization it becomes clear how and which trade-offs can be made while keeping all attributes included in the evaluation. However, no trade-offs should be made with respect to toxic emissions Material into the environment. [ EWASTE.UNEP 0 AS 06/05/2015 ]

This policy could extend to a total ban; for example, the discharge of a toxic product Material into a freshwater body. For such types of pollution, the external costs to the community are far greater than the advantages gained by the polluter, in which case the government simply outlaws such conduct. [ JACLET.EN 0 AS 06/05/2015 ]

Standard copper smelters or hydrometallurgical (leaching) plants however, are not advisable for circuit board treatment due to inadequate handling of toxic substances (such as lead, cadmium or organics) Material and lower metal yields. [ EWASTE.UNEP 0 AS 06/05/2015 ]
