Creation of a “world‑wide ecological problem" and the role of PCB Reassuring customers and government alike though questionable decision-making process

Gerald Markowitz and David Rosner point in their article (reference below): “Industrially produced chemicals have become an essential ingredient in virtually all of our lives. Our kitchens are filled with detergents; household sprays are made from a variety of solvents; our walls and floors are made of ‘vinyl’; our foods are packaged in wrappings made of clear plastics; our vegetables are grown with synthetic fertilizers and covered with pesticides; our computers, desks, and mechanical devices are filled with synthetic materials. It is not surprising that chemicals are in our bodies as well, where literally hundreds of chemicals have been identified”……” Scientists barely understand what long-term dangers these substances may present to human health and the environment. Some of these chemicals are especially worrisome“…….”Of special concern are a variety of chlorinated hydrocarbons, including DDT and other pesticides that were once spread freely………... Despite being banned decades ago, they have accumulated in the bones, brains, and fatty tissue of virtually all of us. Their close chemical carcinogenic cousins, polychlorinated biphenyls (PCBs), were found in innumerable household and consumer products—like carbonless copy paper, adhesives, paints, and electrical equipment—from the 1950s through the 1970s.”
The authors describe in their article the PCB story.
Monsanto, PCBs, and the creation of a "world-wide ecological problem" by Markowitz GRosner D in J Public Health Pol (2018) 39:463–540;

Authors reviewed de-classified Monsanto documents and concluded that manipulative activities such as ghost-writing of research articles occurred

Analyzing, 141 recently de-classified documents, made public during the course of pending toxic tort litigation, In Re Roundup Products Liability Litigation, McHenry has revealed “Monsanto-sponsored ghostwriting of articles published in toxicology journals and the lay media, interference in the peer review process, behind-the-scenes influence on retraction and the creation of a so-called academic website as a front for the defense of Monsanto products”.

Many individuals have been exposed to known lung carcinogens in their work, but, current enrolment criteria recommended by professional organizations in the USA and elsewhere rarely include occupational risk.

“Lung cancer is a leading cause of cancer death worldwide. Five-year survival is 19% for all lung cancers and 55% for localised tumours; average 5-year survival for advanced cases with metastases is only 4.5%. The International Agency for Research on Cancer lists 13 agents with high likelihood of causing lung cancer: ionising radiation, asbestos, silica, nickel, cadmium, chromium, beryllium, arsenic, diesel exhaust, soot, bis(chloro-methyl) ether, coal tar pitch and sulfur mustard. Studies also suggest that there is a more than additive interaction between asbestos and cigarette smoking; it is not yet established if this interaction exists for other lung carcinogens as well”

 Using criteria that include occupational risk Welsh and her colleagues have detected a baseline rate of lung cancer equivalent to that found in the US National Lung Screening Trial, although less than half the cohort met smoking criteria used in that trial.

Systematic review and metaanalysis of greenspace exposure and health outcomes

The health benefits of the great outdoors: A systematic review and metaanalysis of greenspace exposure and health outcomes

Environmental ResearchVolume 166, October 2018, Pages 628-637

In a recent review Caoimhe Twohig-Bennett and  Andy Jones show that:

Greenspace exposure is associated with wide ranging health benefits, with meta-analyses results showing statistically significant associations with reduced diastolic blood pressure, heart rate, salivary cortisol, incidence of type II diabetes and stroke, all cause and cardiovascular mortality, as well as health-denoting associations with pregnancy outcomes, HRV, and HDL cholesterol, and self reported health. The findings of this systematic review suggest that the creation, regeneration and maintenance of accessible greenspaces and street greenery may form part of a multi-faceted approach to improve a wide range of health outcomes.
