আর্সেনিক জনস্বাস্থ্যের জন্য অত্যন্ত বিপজ্জনক বিষ। আর এই আর্সেনিকের কবলে পড়ে আমাদের দেশের বহু মানুষেরই ক্যান্সারসহ নানা রোগে আক্রান্ত হতে হচ্ছে। তবে এবার আশার আলো দেখিয়েছেন বিজ্ঞানীরা। সম্প্রতি এক ধরনের জলজ শৈবাল (Aquatic moss) শনাক্ত করেছেন সুইডেনের গবেষকরা। শৈবালটির বৈজ্ঞানিক নাম warnstofia fluitans।

গবেষকরা বলছেন, এ শৈবালটি পানির আর্সেনিক এমনভাবে বিশুদ্ধ করে যে, তা পান করার উপযোগী হয়ে ওঠে। এ শৈবাল দিয়ে আর্সেনিক মুক্ত করার প্রক্রিয়াও খুব সহজ। পানির মাঝে এ শৈবালটি থাকলেই চলবে। মাত্র এক ঘণ্টাতেই পানির ৮২ শতাংশ আর্সেনিক মুক্ত করতে সক্ষম হয় এ শৈবালটি। বাংলাদেশের বেশ কিছু অঞ্চলে আর্সেনিকের ভয়াবহ আক্রমণ দেখা দিয়েছে। আর সে অঞ্চলের মানুষের মাঝে পানি পরিশোধনের সহজ উপায় হতে পারে এ শৈবালের ব্যবহার।
