Nutrient pollution

Ebook "Physiological, developmental and behavioral effects of marine pollution" covers bio-accumulation and detoxification of contaminants, and the development of tolerance. The major pollutants covered are metals, organic compounds (oil, pesticides, industrial chemicals), nutrients and hypoxia, contaminants of emerging concern, and ocean acidification. Some attention is also devoted to marine debris and noise pollution.​

Ebook "Phytoremediation and biofortification: Two sides of one coin" is a valuable resource to students, technicians, and academics who are interested in the treatment of environmental problems (bioremediation) through the use of plants, and in the field of biofortification. This book shows how, despite having different goals, both phytoremediation and biofortification technologies can be closely connected as they are both based on the phytoextraction process that involves plant uptake, accumulation, and transformation of nutrient elements from soil.

In addition to its effects on air quality, stubble burning also affects soil fertility (through the destruction of its nutrients), economic development and climate. The crop stubbles (if managed properly) could provide immense economic benefits to the farmers and protect the environment from the severe pollution. Some of the alternative management practices include the incorporation of the stubble into the soil, use of stubble as fuel in power plants, use as raw material for pulp and paper industries, or as biomass for biofuel production.

The nutrient pollution index showed moderate to very high pollution while the waterbodies will pose very high non-carcinogenic health risks to users via the oral pathway. Overall, the waterbodies are at risk of eutrophication and efforts should be put in place to reduce anthropogenic activities around the area and thus input of nutrients in these water bodies.

Nghi Son is an economic zone oriented to developing heavy industry and petrochemicals and has potential to become the most substantial economic zone in the North Central region. The zone is also one of the potential waste sources polluting Thanh Hoa coastal waters. Numeric modeling using Delft3D software package with different scenarios: Current status scenario, controlled discharge scenario, and incident scenario was developed to simulate states of some pollutants of organics and nutrients from the zone to Thanh Hoa coastal waters in different periods.

Human urine from domestic wastewater has been considered as an ideal nutrient source for microalgae cultivation due to the high concentration of nitrogen and phosphorus. Moreover, pollution caused by nutrient (N, P) is difficult to treat and costly. In this study, membrane fouling and nutrient removal was evaluated in a membrane photobioreactor (MPBR) system using urine as substrate and microalgae-bacteria as co-cultures under two light - dark cycles.

Crop residues are the plant parts that are left in the field after harvesting. These residues are usually burnt to clear the field as a field preparation for the next crop. Burning residues is the cheapest and common method adapted by farmers. Burning of residues affects the soil health as well as pollute the environment. Due to burning of residue, microbes are killed and making soil unfertile. Besides macro and micro nutrients which are easily volatilized due to burning of residue in the soil.

The excess usage of synthetic fertilizers with minimum application of organic inputs results into nutrient deficiencies, deterioration of soil and also causes environment pollution. It also affects the sustainability of agricultural production. Sustainable agricultural production includes the management of soil organic carbon, use of organic manure such as animal manure, green manure, crop residues, and sewage sludge. Since only organic manure cannot fulfill the nutrient demands of agriculture crops, hence integration of fertilizers and organic sources is the need of the hour.

Burning of crop residues generates large amount of pollutants leads to the cardiorespiratory diseases. Also, it has negative impact on organic matter, nitrogen and other micro and macro soil nutrients. Soil incorporation of crop residues is one of the best alternatives to the crop residue burning. Sunflower, having most of the cultivable area in Karnataka and Maharashtra has proved to be very beneficial for the improvement of soil productivity.

A comprehensive study was conducted on the distribution of earthworms and soil analysis in the Polluted area of Palakkad district. There are some exotic and native peregrine species which has the inherent ability to withstand in disturbed habitats. Such earthworm species have high medicinal value due to the presence of immunologically active compound in their body. The present study reveals that four different species of earthworms was identified from the sampling stations and analysed the influence of the soil parameters like macro and micro nutrients on earthworm diversity.

Agriculture is going through a profound revolution worldwide due to increasing world demand for food, higher costs of energy and other inputs, environmental pollution problems, and instability of cropping systems. The importance of plant functioning can be realized from the facts that knowledge of mineral nutrition of plants has opened new vistas for fertilizer practices. The detection of deficiencies and toxicity of particular mineral nutrient element has enabled us to make adequate soil amendments and root nutrient absorption for better plant growth.
