கேள்வி: மீன்களில் பாதரசம் பற்றி தகவல் சொல்.
பதில்: மீன்களின் உடலில் பாதரசம் சேர்கிறது. அதிலும் குறிப்பாக மெத்தில்-பாதரசம் என்னும் வடிவில் சேர்கிறது. இது மிகவும் நச்சுத் தன்மையுள்ளது. நீர் மாசுபாட்டின் காரணமாக கன உலோகங்கள் மீன்களின் உடலில் வெவ்வேறு அளவுகளில் கண்டறியப்பட்டுள்ளன. நீண்ட நாட்கள் வாழக்கூடிய உணவுச் சங்கிலி மேலே உள்ள மீன்களான சுறா, சூரை போன்ற மீன்களில் மற்ற மீன்களை விட பாதரசம் அதிகம் காணப்படுகிறது.The mercury levels in the table, unless otherwise indicated, are taken from: [https://www.fda.gov/Food/FoodborneIllnessContaminants/Metals/ucm115644.htm Mercury Levels in Commercial Fish and Shellfish (1990-2010)] U.S. Food and Drug Administration. Accessed 8 January 2012. மனித உடலிலும் பாதரசம் சேர்கிறது. எனவே இந்த பாதரசம் மிகுந்த மீன்களை உண்ணும் போது மனிதர்களில் அதிகமான அளவில் பாதரசம் சேர்ந்து பாதரச நச்சு ஏற்படுத்தக்கூடும். மைய நரம்பு மண்டலத்தைப் பாதிக்கக்கூடியதாக பாதரசம் இருப்பதால் இயற்கைச் சூழலுக்கும் மனிதர்களுக்கும் இது கேடு தருவதாக உள்ளது. பாதரசமுள்ள மீன்களை உண்பது குறிப்பாக கருவுறக்கூடிய அல்லது கருவுற்ற பெண்கள், பாலூட்டும் தாய்மார்கள், சிறுவர்கள் ஆகியோருக்கு பாதிப்பை ஏற்படுத்தக்கூடும். {| class="wikitable sortable collapsible" |- ! colspan="8"| விற்கப்படும் மீன்களிலும் இறால் வகைகளிலும் உள்ள பாதரசத்தின் அளவு |- ! class="unsortable" | ! இனம் !
