Ozone-Depleting Substances and Fluorinated Greenhouse Gases (Amendment etc.) (EU Exit) Regulations 2020

Baroness Jones of Moulsecoomb Excerpts

Wednesday 9th December 2020 Grand Committee

[Baroness Jones of Moulsecoomb (GP) [V]]

My Lords, I will focus on mercury today, not because ozone-depleting substances, fluorinated greenhouse gases and indeed detergents are not extremely important but because mercury is so toxic and is in use for quite a number of developmental practices. I am quite concerned that it should be taken very seriously.

Exposure to mercury is a huge problem. There is a sort of global pool that moves around between air, water, sediment, soil and, of course, organisms, including ourselves. It is a highly toxic metal which causes significant harm to human health and to ecosystems. Of particular concern are the levels of mercury in seas and oceans, where mercury accumulates up the food chain and reaches humans in concentrated mass through the consumption of seafood—it has certainly put me off seafood. The most damaging human health impact is exposure of pregnant women and unborn children, with permanent impacts on brain function, so we absolutely have to take it seriously and make sure that we are doing as much as we can to render it safe.

The EU has taken the problem of mercury very seriously. It has implemented the legislation that we are discussing today and set Europe the goal of becoming mercury-free, which is quite an ambition. Is it the Government’s intention to continue to reduce our use of mercury to zero? When will the UK eliminate mercury usage entirely? Also, will the Government do something about it internationally? We have all read newspaper stories about children looking for gold and using mercury to separate the gold out, which is absolutely horrific. Perhaps it is done already—I do not know—but there is an argument for labelling all gold from that sort of production process “mercury gold” and explaining to people why perhaps they should not buy it. It is part of our role as an engaged nation to deal with this problem internationally. It is not something that we can turn our back on. Also, mercury-polluted sites can wash out into watercourses, where mercury is released into the air. What are the Government going to do to decontaminate mercury from the environment and remediate damaged ecosystems?

I hope that the Minister can answer my questions. If not, perhaps he will write to me.
