These trace metals were associated with leaded petrol — which hasn’t been used since 2002 — and industrial emissions, which include past metal processing, fossil fuel burning, refineries, transport and power generation.
In most infected individuals, the virus does not cause serious illness. However, it causes a very serious respiratory disease — and even death — in a minority of patients. Through many studies of people with COVID-19 over the past few months, we have learned what characteristics are more likely to be linked to mild versus severe forms of the disease.
As a philosophy professor who’s worked on food issues for my entire career, I’ve come to believe that questions of animal welfare are more complicated than they seem at first glance.
Studies that suggest that the microbiome can influence human health or disease are often challenged because it is hard to distinguish between cause and effect.

It may be some time before we fully understand whether a less diverse microbiome leads to obesity, or if obesity leads to a less diverse microbiome.
Cold plasma is unique because it mainly produces hot (highly energetic) electrons – these particles are great for breaking down the chemical bonds of plastics. Electricity for generating the cold plasma could be sourced from renewables, with the chemical products derived from the process used as a form of energy storage: where the energy is kept in a different form to be used later.
