Applying biochar to soil has been shown to improve carbon sequestration and soil health, and remediate contaminated soil and water resources. Biochar is valuable as a nutrient source and a soil amendment, to remediate contaminated soil and aquatic ecosystems.
Plastics can pollute the air, land and water during all stages of their life cycle from manufacture to disposal. Synthetic plastics do not biodegrade and tend to accumulate in the environment. Particulate plastics of varying physical size fractions are becoming major sources of pollutants in terrestrial and aquatic ecosystems.
Controlling the quality of irrigation water is important for crop and plant growth. Water quality can be monitored in situ using an ion-selective electrode (ISE) array with suitable data processing algorithms.
Elevated nitrate concentration is a multifaceted problem. In surface water and groundwater, it can cause eutrophication. When present in drinking water, nitrate can threaten human health – for example, it can cause methemoglobinemia in infants. Thus, finding a way to remove nitrates from water is important for human and environmental health.
In the past, the assessment and management of groundwater contamination has been driven by contaminant concentrations. However, concentration data alone are sometimes not sufficient to fully understand the behaviour or effect of a plume over time.
