Research problems linked to this topic
- The quality of drinking water is of the vital concern for human health and life.
- With the rapid development of economy and society, environmental pressure is increasing and environmental problems are emerging.
- Climate change and rapid urbanization are driving the need for improved urban stormwater runoff strategies.
- Climate change is a major environmental concern and the melting processes of the glaciers and snow-packs are sensitive to climate change.
- Chlorinated and non-chlorinated organic contaminants occur widely in both surface and ground water systems and these contaminants pose risks to humans and other living organisms.
- Water quality is sensitive to changes in landscape patterns in a watershed, particularly during urbanization.
- Climate change and sea-level rise have combined with other factors resulting in major losses of intertidal salt marshes.
- Mining and processing of mineral resources causes the technological environmental impact, including the vegetation.
- High nutrient loads to streams, lakes, and oceans are known to adversely affect water quality and may potentially cause algae blooms.
- Most research on hydrological risks focuses either on flood risk or drought risk, whilst floods and droughts are two extremes of the same hydrological cycle.
- The essence of hazard and risk assessment of chemicals (Chapter 1) is the comparison of exposure (the concentration of the substance assessed in the environment) with effects (the highest concentration at which no effects are expected to occur on organisms or ecological systems).
- Global environmental concerns have become more common as governments and citizens alike become better educated with the issues that relate political discussions with scientific interests and understanding.
- Large amounts of waste are generated each day in the world, being a major concern for the EU28, who establish waste management as a priority line of work within the Horizon 2020.
- Rapid urbanisation and industrialization have made significant increase in demand for water.
- The urban heat island effect, exacerbated by rising average surface temperatures due to climate change, can lead to adverse impacts on city populations.
- Anthropogenic activity such as damming or diversion of rivers cause extensive disturbance to ecosystems, as well as the interaction between surface water and groundwater.
- Human activities disturb the land surface of the earth, and thereby alter natural erosion rates.
- Anthropogenic disturbances to streams have been shown to cause channel instability resulting in increased sedimentation and altered substrate composition.
- Overheating in buildings has been identified as an essential cause of several problems ranging from thermal discomfort and productivity reduction to illness and death.
- The determination of detectable amounts of lead contamination in blood, foods and biological materials has been a recent problem in relation to the operation of lead mining
- Increasing concern is being felt by scientists and laymen alike over the possibility of climate alteration due to increased atmospheric dust.
- Treatment policies for debris from Fukushima Daiichi Nuclear Power Station have not been decided yet.
- With growing population and urbanization, there is an increasing exploitation of natural resources, and this often results to environmental pollution.
- Human activities have resulted in rising temperatures and the introduction or extirpation of top predators worldwide.
- Buildings and built areas may suffer from severe damage caused by forest and wild land fires.
- The presence of heavy metal concentrations was examined in surface sediments from 27 sites within the Odiel river in the southwest Spain suffering inputs from industrial and mining activities.
