What is Pollution Prevention?

Published

Pollution is the contamination of air, soil, or water by the discharge of harmful substances. Pollution prevention is the reduction or elimination of pollution at the source (source reduction) instead of at the end-of-the-pipe or stack. Pollution prevention occurs when raw materials, water, energy and other resources are utilized more efficiently, when less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process. By reducing the use and production of hazardous substances, and by operating more efficiently we protect human health, strengthen our economic well-being, and preserve the environment.

Source reduction allows for the greatest and quickest improvements in environmental protection by avoiding the generation of waste and harmful emissions. Source reduction makes the regulatory system more efficient by reducing the need for end-of-pipe environmental control by government.

NPPR supports multi-media P2 approaches which work to solve environmental problems holistically and do not only focus on pollution in a single medium (air, land, or water). Well-intentioned rules, regulations and solutions that are not multi-media sometimes exacerbate existing conditions by creating larger problems to other media that are not accounted for by a single media-specific solution. Many times this can result in the transfer of pollution from one medium to another. For example, in some cases, by requiring hazardous air emission controls for industrial facilities, other problems might result, such as pollutants being transferred to underground drinking water through the residual sludge.

What are the Economic Incentives for Pollution Prevention?

Adopting pollution prevention practices and techniques often benefits industry by lowering a company’s operational and environmental compliance costs. By preventing the generation of waste, P2 can also reduce or eliminate long-term liabilities and clean-up costs. Furthermore, disposal costs are reduced when the volume of waste is decreased. This can also lead to a reduction in workplace exposures to hazardous materials which can affect workers’ health and hence, their productivity. If less waste is produced, there will also be a diminished need for on-site storage space. Furthermore, by preventing pollution there will be a greater likelihood that a company will be in compliance with local, state, and federal compliance statutes. Finally, as community pillars, businesses shoulder an important responsibility for protecting the environment and natural resources for their own good as well as that of society.

New blood test in pregnancy to predict autism risk in babies

New York, Sep 22: Researchers have developed a novel blood test for pregnant mothers that can, with nearly 90 per cent accuracy rate, predict the probability of having a child that will be diagnosed with autism.

According to studies, if a mother has previously had a child with autism, the risk of having a second child with the developmental disorder is approximately 18.7 per cent, whereas the risk in the general population is approximately 1.7 per cent.

In the study, led by Juergen Hahn, Professor at Rensselaer Polytechnic Institute in New York, metabolites of the folate-dependent transmethylation and transsulfuration biochemical pathways of pregnant mothers were measured to determine whether or not the risk of having a child with autism could be predicted by her metabolic profile.

Pregnant mothers who have had a child with autism before were separated into two groups based on the diagnosis of their child whether the child had autism or not.

Then these mothers were compared to a group of control mothers who have not had a child with autism before.

The results, appearing in the journal Research in Autism Spectrum Disorders, showed that while it is not possible to determine during a pregnancy if a child will be diagnosed with autism by age 3, they did find that differences in the plasma metabolites are indicative of the relative risk (18.7 per cent vs 1.7 per cent) for having a child with autism.

“These are exciting results as they hint at differences in some metabolic processes that potentially play a role in increasing the risk of having a child with autism,” Hahn said.

“However, it would be highly desirable if a prediction based upon physiological measurements could be made to determine which risk group a prospective mother falls into,” Hahn noted.

Eat fish thrice a week to boost your unborn’s eyesight, brain

London, Sep 21: Pregnant women can enhance the development of their unborn child’s eyesight and brain function by regularly eating fatty fish during the pregnancy, a new study has found.

The findings suggested that infants whose mothers ate fish three or more times a week during the last trimester of their pregnancy fared better than those whose mothers ate no fish or only up to two portions per week.

“The results of our study suggest that frequent fish consumption by pregnant women is of benefit for their unborn child’s development,” said lead author Kirsi Laitinen of the University of Turku in Finland.

“This may be attributable to long-chain polyunsaturated fatty acids within fish, but also due to other nutrients like vitamin D and E, which are also important for development,” Laitinen added.

For the study, published in the journal Pediatric Research, the research team analysed the results of a small group of mothers and their children drawn from a larger study.

The mothers had to keep a regular food diary during the course of their pregnancy. Fluctuations in their weight before and during pregnancy were taken into account, along with their blood sugar level and blood pressure.

The team recorded the levels of nutritional long-chain polyunsaturated fatty acid sources in the mother’s diet and blood serum, and the levels in the blood of their children by the age of one month.

Their children were further tested around their second birthday using pattern reversal visual evoked potentials (pVEP). This sensitive and accurate, non-invasive method is used to detect visual functioning and maturational changes occurring within a young child’s visual system.

“Our study therefore highlights the potential importance of subtle changes in the diet of healthy women with uncompromised pregnancies, beyond prematurity or nutritional deficiencies, in regulating infantile neurodevelopment,” Laitinen noted.

Eating food cooked on wood, coal may impair your lungs

New York, Sep 21: Love to eat food cooked on the barbecue? Beware, it is associated with increased risk of respiratory illness or death, researchers warned.

Compared to those who used electricity or gas, chronic and acute respiratory disease hospitalisations or deaths were 36 per cent higher among those who used wood or coal for cooking, researchers, from the University of Oxford, have found.

People who switched from solid fuels to clean-burning fuels reduced their risk to only 14 per cent higher than those who never cooked with wood or coal.

It is because solid fuels emit very high levels of pollutants especially very small particles, which penetrate deep into lungs, the researchers explained.

“The increased risk of major respiratory diseases posed by burning wood or coal can be significantly lowered by switching to a clean-burning fuel”, said Zhengming Chen, professor at the varsity’s Nuffield Department of Population Health.

“Our findings make a compelling case to speed up the global implementation of universal access to affordable clean energy, one of the UN Sustainable Development Goals,” Chen said.

Nearly three billion people around the world live in households that regularly burn wood, coal or other solid fuels to cook their food.

Typically, these households are found in the rural areas of low- and middle-income countries.

For the study, published in the journal American Thoracic Society, the team analysed the health records of 280,000 adults, aged 30 to 79 from 10 areas of China.

They were followed for nine years and 19,823 were either hospitalised or died following major respiratory diseases.

Of these events, 10,553 were due to asthma or chronic obstructive pulmonary disease (COPD), and 7,324 were due to acute lower respiratory infections, most often pneumonia.
