Correction: Mukherjee et al. Heavy Metal and Metalloid Contamination in Food and Emerging Technologies for Its Detection. Sustainability 2023, 15, 1195

The authors would like to make the following corrections to the published paper [1]. The changes are as follows:

(1) At the end of the first paragraph in “Section 2.2. Lead (Pb) Toxicity”, an extra reference needs to be added. The reference number [26] should be changed to [26,27].

(2) Replacing the second paragraph in “Section 2.4. Tin (Sn) Toxicity” on page 6:

“It has been calculated, however, that a Western adult could consume an additional 109.1 mg of Sn per day, with the vast majority of this amount coming from fruits (fruits contain 500 mg/kg of Sn, while meat contains 2 mg/kg, potatoes contain 22 mg/kg, spinach contains 2 mg/kg, and cereals contain 47 mg/kg) [55]”.

“It has been calculated, however, that a Western adult could consume an additional 109.1 µg of Sn per day, with the vast majority of this amount coming from fruits (fruits contain 500 µg/kg of Sn, while meat contains 2 µg/kg, potatoes contain 22 µg/kg, spinach contains 2 µg/kg, and cereals contain 47 µg/kg) [49,55]”.

(3) At the end of the second paragraph in “Section 2.4. Tin (Sn) Toxicity”, an extra reference needs to be added. The reference number [55] should be changed to [49,55].

(4) In Section 2.4, the lines “Maximum allowable levels of Sn in food are usually 250 mg/kg (200 mg/kg in the UK) for solid foods and 150 mg/kg (2.5 mmol/L) for liquids, with a PTWI of 14 mg/kg body weight” have a typo error. They should be replaced with

“Maximum allowable levels of Sn in food are usually 250 mg/kg (200 mg/kg in the UK) for solid foods and 150 mg/kg for beverages, with a PTWI of 14 mg/kg body weight”.

In similar fashion, the data in Table 1 in the section Tin (Sn) should be modified with similar data, so we need to replace the original Table 1 and we added the word “problems” after “Parkinson’s disease, with tremors and facial muscle” in Table 1.

(5) In Section 4.2, reference number [148] is mistakenly cited and should be replaced with the following references: [144,145].

(6) In Section 4.4, reference [164] should be cited at the end of line “However, the complex matrix with high salt concentration makes it challenging to examine their As content.”

(7) At the end of Section 3.3, reference number [131] should be changed to [127,131].

(8) In Section 4.1, in the second paragraph, there is a typo error in the statement. The sentence “Pb concentrations of 0.040–0.25 mg/kg had a repeatability relative standard deviation of 20–50%, Cd concentrations of 0.001–0.51 mg/kg had a range of 12–352%, Zn concentrations were 0.7–8.0%, Cu concentrations were 0.5–45%, and Fe concentrations were 11–14% [133].” should be replaced with

“Pb concentrations of 0.040–0.25 mg/kg had a repeatability relative standard deviation of 20–50%, and Cd concentrations of 0.001–0.51 mg/kg had a range of 12–352%. Ranges were from 4 to 8% for zinc concentrations of 0.7–38 mg/kg, from 7 to 45% for Cu concentrations of 0.51–45 mg/kg, and from 11 to 14% for Fe concentrations of 4–216 mg/kg [133].”

(9) Accordingly, the reference numbers in the reference list should also be updated. We have renumbered the references starting with [27–31,148–270].
