من الجنين إلى البالغ، الميكروبلاستيك يلوث أجسامنا – هل يمكن للذكاء الاصطناعي والتحفيز الضوئي الموجه أن يساعدا؟

Artificial Intelligence (AI) is such a tantalizing technology for many reasons.  However, above all, it is its versatility that makes it potentially world-changing.  Whether it be intuitive analytics, the development of medicines and healthcare procedures, or simply task automation – AI is set to play a massive role in the future we are building today.  To that end, a team of researchers at the University of Waterloo (U of W) has recently released a study that looks to leverage the technology to address the growing problem of microplastics in our world today.

فهم الميكروبلاستيك

Before diving into how AI can help us address microplastics, it is important to first learn what the term means and why they are so harmful to the human body and our environment.

ما هي الميكروبلاستيك؟

Microplastics are tiny plastic particles that measure less than 5 millimeters in diameter.  They originate from various sources, including the breakdown of larger plastic waste, microbeads in personal care products, and synthetic fibers shed while washing clothes.

Sadly, our reliance on such materials means that microplastics are now pervasive in the environment.  They are found in oceans, freshwater systems, and even in the air.  This is partly because their small size makes them easily transportable across different ecosystems and even more difficult to remove once they have entered the environment.

المخاطر المرتبطة

The danger of microplastics lies in their size and longevity.  Due to their small size, they can be ingested by wildlife and enter the food chain, potentially causing physical and chemical harm to organisms.  Microplastics can absorb and concentrate toxic substances from the surrounding environment, which may then be transferred to organisms that ingest them.  This is particularly concerning given that in recent years, we have already begun في اكتشاف وجود الميكروبلاستيك في المشيمة البشرية.

بالإضافة إلى ذلك، فإن انتشارها الواسع ومتانتها يعني أنها تتراكم في النظم البيئية أسرع مما تتحلل، مما يشكل مخاطر بيئية وصحية طويلة الأمد.

The full extent of their impact on human health is still under investigation, but growing concern exists about their potential to cause harm.

ما الذي يتم عمله بشأن الميكروبلاستيك؟

Thankfully, there are already research teams worldwide working to address and one day solve the growing issue of microplastics.  The following are a couple of examples of this that will hopefully result in such approaches being adopted en masse.

الذكاء الاصطناعي

As mentioned, an interdisciplinary team at the University of Waterloo is already pioneering the use of AI to tackle the growing problem of microplastic pollution.  Recently, the team بتفصيل جهوده في دراسة that saw it utilize advanced AI in identifying microplastics more efficiently and accurately.

The team’s AI tool, PlasticNet, employs deep learning and spectroscopy to discern the unique “fingerprints” of these particles, allowing for faster and more precise identification.  This is particularly beneficial for various industries, including,

• معالجة مياه الصرف الصحي
• إنتاج الأغذية

These industries play a large role in ensuring widespread access to clean drinking water for a huge portion of the Earth’s population, and any advancements in their ability to treat or prevent the distribution of microplastics can have huge environmental and health impacts.

As part of the study, PlasticNet has already been shown to be a successful tool in a local wastewater treatment plant. It demonstrated its potential through the enhancement of the microplastic detection and removal processes, marking a significant step towards a sustainable future.

التحفيز الضوئي الموجه

Beyond AI, other approaches, such as’ light-driven photocatalysis ,’ are being explored to reduce microplastics.  This was recently demonstrated by another team of researchers led by Professor Shizhang Qiao from the University of Adelaide, who presented a solution to polyethylene waste by using the process to transform it into valuable chemicals.  More specifically, the team states that with this approach it,

…إعادة تدوير نفايات البلاستيك البولي إيثيلين إلى إيثيلين وحمض البروبيونيك بانتقائية عالية باستخدام محفزات معدنية موزعة ذريًا،

While not all microplastics are polyethylene, it remains extremely common and widespread.

Interestingly, these findings could synergize with AI technologies, especially in optimizing the process and enhancing the precision of chemical conversion.  AI could aid in monitoring and adjusting the photocatalytic reactions in real-time, ensuring maximal efficiency and selectivity.  This integration could lead to more sustainable waste management practices and advance the development of a circular economy, addressing both environmental concerns and the need for valuable chemical products.

ماذا يمكنك أن تفعل؟

For those who are conscious of their environmental footprint, you may wonder if there is anything you can do to prevent microplastics from dispersing.  The following are a few easy examples of common habits that will make a difference when adopted en masse.

تقليل البلاستيك ذو الاستخدام الواحد: قد يبدو هذا تافهًا، لكن استخدام البلاستيك ذو الاستخدام الواحد مثل القش، الأدوات، الأكياس، إلخ، يتراكم إلى كميات كبيرة عبر السكان. ببساطة اختيار الخيارات القابلة لإعادة الاستخدام يمكن أن يحدث فرقًا ملحوظًا. ومن الجدير بالذكر، هناك أمثلة بالفعل على مبادرات حكومية تتصدى لهذا.

بدائل الأقمشة الطبيعية: كلما كان ذلك ممكنًا، اختر شراء وارتداء الملابس المصنوعة من الألياف الطبيعية مثل الصوف، حيث أن المواد الاصطناعية الشائعة مثل الفليس غالبًا ما تُصنع من بولي إيثيلين تيريفثاليت (PET).

These are just two examples of habit changes that have the potential to make a difference.  Whether you choose to adopt them, begin using metal bottles over plastic, or some other approach, it all adds up.

الجهات الفاعلة في الصناعة

As it stands, the above studies are just a glimpse at what the future may hold.  Such practices must still be fleshed out and perfected before being implemented commercially and at scale.  For now, the following are a few examples of companies working to achieve just that, taking the invaluable insights provided by such research teams and building atop it.
