Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.

Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

My hon. Friend makes a really good point, which I will address later. He is absolutely right; there are alternatives, and many manufacturers are looking to convert to them. Ground coconut husk and apricot kernels are other examples of things that could replace microbeads in cosmetics and personal care products.

There is lots of visible plastic pollution and rubbish. Plastic bags, bottles and fishing detritus such as discarded ropes and lines are all polluting our oceans and seas, but it is the less obvious tiny particles—microbeads of less than 5 mm—that present a real danger to shellfish and fish, which often ingest them mistaking them for food. It is estimated that a total of 15 trillion to 51 trillion microplastic particles have accumulated in the oceans. This debate is about plastic microbeads, and in particular their use in cosmetic and personal care products.

Recent studies suggest that these minuscule dots of plastic, when washed into the ocean, could represent a threat to humans as a result of eating fish. One study revealed that in 2009, microplastics were found in 36.5% of fish caught by trawlers in the English channel. Sir David, I do not know if you are a fancier of oysters, but for every six oysters consumed, one might consume 50 microbeads.

Microbeads are tiny balls of polyethylene and other plastics derived from petrochemicals, including polypropylene and polystyrene. They are used in a wide range of cosmetic products, including exfoliators, shower gels, whitening toothpaste and face washes, as well as in many abrasive cleaning products. Interestingly, though we are not talking about this today, fleeces also contain plastic microfibers, and when one puts on one’s car brakes, the tyres fray, which is another way that microfibres find their way into the watercourses.

How do microbeads get into the sea? If they could be removed once they had been washed down the drain, there would not be a problem, but in evidence on the environmental impact of microbeads taken by the Environmental Audit Committee, on which I was delighted to sit, it became apparent that removing them is a very tricky process and few water companies have the sophisticated filtration systems needed to do it. As a result, many of these products, complete with their microplastics, are flushed down the drain during our daily ablutions and end up in the watercourses and ultimately the sea.

Scientists have demonstrated that fish exposed to microplastics during their development can show stunted growth and increased mortality rates, as well as changed behaviour that could endanger their survival—especially reduced hatching rates. An article was published in Science relating to that. Estimating the toxicity of microplastics is complex and the full dangers to human health are not fully quantified yet, but studies have revealed that these plastics are entering the food chain, although the full impact is hard to measure. Microplastics can release and adsorb toxic chemicals and may act as a vector for them, transferring contaminants to organisms that ingest microplastics. I am heartened that Government sources have stated that the chief scientific adviser will review the effects on human health in future.

One fifth of microbeads are used in the cosmetics and personal care industry, and some 680 tonnes of plastic microbeads are used in cosmetic products in the UK every year. This is an important industry, worth £10 billion in the UK in 2016, and we have the second largest cosmetics market in Europe. It makes a significant contribution to our economy, not to mention the fact that it keeps us clean and beautiful, and I am the first to say that I enjoy using make-up and all these products. It is very important that we do not damage the industry, but surely the industry does not want to have on its conscience any associated link with damage the environment. With the right science behind it, the industry could turn to alternatives, as my hon. Friend the Member for Cheltenham (Alex Chalk) said. Indeed, many companies are doing that.

I congratulate the hon. Lady on securing this debate. Manufacturers get a little worried when there is the possibility of a ban. Does she agree that there is therefore a greater incentive for them to get on with researching and implementing substitutes and replacements quickly, before we implement a ban?

The hon. Gentleman makes an excellent point. The Government have made it quite clear that something is coming in terms of a ban. Many companies are planning ahead, and those that are not certainly ought to be.
