Abstract
Biosolids can provide a nutrient rich soil amendment, particularly for poor soils and semi-arid or drought-prone areas. However, there are concerns that sludge and biosolids could be a source of propagation and exposure to AMR determinants such as antibiotic resistant bacteria (ARB), and antibiotic resistance genes (ARGs). To inform risk assessment efforts, a systematic literature review was performed to build a comprehensive spreadsheet database of ARB and ARG concentrations in biosolids (and some sludges specified as intended for land application), along with 69 other quantitative and qualitative meta-data fields from 68 published studies describing sampling information and processing methods that can be used for modeling purposes. Mean ARG concentrations per gram in positive samples of biosolids ranged from −5.7 log 10 (gene copies [gc]/g) to 12.92 log 10 (gc/g) (with these range values reported per dry weight), and aqueous concentrations ranged from 0.9 log 10 (gc/L) to 14.6 log 10 (gc/L). Mean ARB concentrations per gram of biosolids ranged from 2.02 log 10 (colony forming units [CFU]/g) to 9.00 log 10(CFU/g) (dry weight), and aqueous concentrations ranged from 3.23 log10 (CFU/L) to 12.0 log 10 (CFU/L). ARG log removal values (LRVs) during sewage sludge stabilization were calculated from a meta-analysis of mean concentrations before and after stabilization from 31 studies, ranging from −2.05 to 5.52 logs. The classes of resistance most relevant for a risk assessment corresponded to sulfonamide (sul1 and sul2), tetracycline (tetZ, tetX, tetA and tetG), beta-lactam (blaTEM), macrolide (ermB and ermF), aminoglycoside (strA and aac(6′)-Ib-cr), and integron-associated (intI1). The resistance classes most relevant for ARB risk assessment included sulfonamides (sulfamethoxazole and sulfamethazine), cephalosporin (cephalothin and cefoxitin), penicillin (ampicillin), and ciprofloxin (ciprofloxacin). Considerations for exposure assessment are discussed to highlight risk assessment needs relating to antimicrobial resistance (AMR) associated with biosolids application. This study aids in prioritization of resources for reducing the spread of AMR within a One Health framework.
