초록

갑각류 중금속 기준은 납과 카드뮴의 경우 각각 0.5 mg/kg과 1.0 mg/kg 이하이다. 비소, 수은, 메틸수은 및 주석은 현재 노출 수준을 고려하여 지속적인 오염도를 조사하고 있다. 이를 기반으로 정부에서는 노출 점유율, 검출률, 오염도가 높은 다소비 식품 목록을 공유하여 수입·유통검사에 활용하고 있다. 새우류는 연안의 유기물질이 많이 포함된 모래나 진흙질, 해조가 많은 곳, 하구 등에 서식하기 때문에 잠재적으로 중금속에 노출될 가능성이 큰 것으로 알려져 있다. 본 연구에서는 새우류 중 특정 중금속의 기준치를 초과하는 품목 그리고 기준치가 없는 경우 검출치 최상위 품목을 판매에서 제외하는 경우 소비자 불안 감소 및 안심도 제고의 화폐적 가치를 측정하였다. 가상가치평가법을 이용하여 소비자 지불의사를 도출하였는데, 질문방식은 개방형직접질문과 지불카드방식을 이용하였다. 도출된 지불의사를 국내 가구 수에 접목하여 총효용을 추정한 결과, 363.9억 원으로 나타났다. 본 연구의 결과는 수산물 중금속에 대한 특정 정책이 소비자의 불안감 감소와 심리적인 안심감을 어느 정도 제고시켜주는지에 대한 실증분석 결과를 제공한다. 이는 식품 안전성이 높아지고 중금속으로 인한 질병에 걸릴 확률이 감소하는 것에 대해서 소비자가 느끼는 가치를 제시해준다.

The standards for heavy metal levels in crustaceans are 0.5 mg/kg and 1.0 mg/kg or lower for lead and cadmium, respectively. Further, the contamination levels of arsenic, mercury, methyl mercury, and tin are being continuously investigated, considering their current exposure levels. Shrimps are potentially exposed to heavy metals because they inhabit areas with abundant organic matter, such as sandy or muddy shores, places with a lot of seaweed, and estuaries. This study measured the monetary value of reducing consumer anxiety and increasing consumer confidence if the government prohibits the sale of shrimp species that exceed the threshold for specific heavy metals and of the top shrimp species for which no threshold for heavy metals is specified. We derived consumer willingness-to-pay (WTP). Combining the estimated WTP with the number of households in the country, the total value of benefits was estimated to be 363.9 billion won. The results of this study will provide an important empirical finding, showing to what extent specific policies regarding heavy metals in seafood can alleviate consumer anxiety and provide psychological reassurance.
