The purpose of our study was to investigate the migration level of lead (Pb), cadmium (Cd), antimony (Sb), arsenic (As), hexavalent chromium ($Cr^{6+}$) and mercury (Hg) from cookwares into food simulants and to evaluate the safety of each heavy metals. The test articles for heavy metals were glassware, ceramics, enamel, earthenware, polypropylene and polyethylene cookwares for Pb and Cd, enamel for Sb, earthenware for As, polyethylene and polypropylene cookwares for $Cr^{6+}$ and Hg. All the article samples of 391 intended for contact with foods were purchased in domestic markets. Pb, Cd, Sb and As were analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), $Cr^{6+}$ by UV visible spectrophotometer and Hg by mercury analyzer. The migration levels of heavy metals in all the samples were within the migration limits of Ministry of Food and Drug Safety (MFDS). As a result of safety evaluation, our results showed that the estimated daily intakes (EDI, mg/kg bw/day) were $9.12{\times}10^{-6}$ and $8.83{\times}10^{-7}$ for Pb and Cd from ceramics and $1.19{\times}10^{-5}$, $1.23{\times}10^{-5}$ and $7.52{\times}10^{-6}$ for Pb, Cd and Sb from enamel. Tolerable daily intakes (TDI, mg/kg bw/day) were established respectively as 0.0036, 0.00081, 0.0021, and 0.0006 for Pb, Cd, As and Hg by JECFA (Joint FAO/WHO Expert Committee on Food Additives), as 0.0060 for Sb by WHO (World Health Organization). When comparing with TDIs, the EDIs accounted for 0.25% and 0.11% for Pb and Cd from ceramics and 0.33%, 1.52% and 0.13% for Pb, Cd and Sb from enamel.

As a result of a close review focusing on the case of obstruction of epidemiological investigation by a religious group A in Daegu, which was a problem when the pandemic of Covid-19 infection began in Korea around February 2, 2020, when an epidemiological investigator requested a specific group to submit a list, While there have been cases where an act of not responding or submitting an edited omission list was sentenced to the effect that the act did not fall under an epidemiological investigation, in the case of non-submission of the visitor list for the B Center, even though a 'list of visitors' was requested. Regarding the fact of refusal without a justifiable reason, 'providing a list of persons entering the building is a key factual act that forms a link between epidemiological investigations accompanying an epidemiological investigation, and refusing to do so is also an act of refusal and obstruction of an epidemiological investigation. There are cases where it is possible to demand criminal punishment. Regardless of whether the request for submission of the membership list falls under the epidemiological investigation, there are cases in which the someones' actions correspond to the refusal or obstruction of the epidemiological investigation. A lower court ruling that if an epidemiological investigation is rejected or obstructed as a result of interfering with factual acts accompanying an epidemiological investigation, comprehensively considering whether or not the list has been diverted for purposes other than epidemiological investigation, the logic is persuasive. Epidemiological investigations such as surveys and human specimen collection and testing are conducted for each infectious disease patient or contact confirmed as a result of the epidemiological investigation, but epidemiological investigations conducted on individual individuals cannot exist independently of each other, and the This is because the process of identification and tracking is essential to an epidemiological investigation, and if someone intentionally interferes with or rejects the process of confirming this link, it will result in direct, realistic, and widespread interference with the epidemiological investigation. In this article, ① there are differences between an epidemiological investigation and a request for information provision under the Infectious Disease Control and Prevention Act, but there are areas that fall under the epidemiological investigation even in the case of a request for information, ② Considering the medical characteristics of COVID-19 and the continuity of the epidemiological investigation, the epidemiological investigator the fact that the act of requesting a list may fall under the epidemiological investigation, ③ that the offense of obstructing the epidemiological investigation in certain cases may constitute 'obstruction of Performance of Official Duties by Fraudulent Means', and ④ rejecting the request for information provision under the Infectious Disease Control and Prevention Act from September 29, 2020 In this case, it is intended to be helpful in the application of the Infectious Disease control and Prevention Act and the practical operation of epidemiological investigations in the future by pointing out the fact that a new punishment regulation of imprisonment or fine is being implemented.
