This paper presents a reusable polymer lab chip sensor for continuous and on-site heavy
metal monitoring in nature. In particular, detection of lead (Pb (II)), which is the most common …

An on-site analyzer system for monitoring of heavy metals has been presented. This
analyzer can automatically perform long-term continuous water sampling and on-site heavy …

Pollution due to heavy metals is becoming increasingly hazardous; therefore, demand for
the large-scale deployment of sensor nodes for water quality monitoring has increased. The …

This paper presents an environmentally friendly disposable heavy metal ion sensor for in
situ and online monitoring in the nature and physiological systems. The miniaturized sensor …

A bismuth-modified electrode can increase the sensitivity of lead and cadmium detection.
However, use of a bismuth-modified electrode in the detection of copper remains limited …

Levels of lead (Pb) in tap water that are well below established guidelines are now
considered harmful, so the detection of sub-parts-per-billion (ppb) Pb levels is crucial. In this …

A compact, durable, low-reagent-usage, portable miniaturized electrochemical sensor is
successfully developed for the high sensitivity detection of trace lead. We fabricated …

This work demonstrates determination of lead (Pb) in surface water samples using a low-
cost copper (Cu)-based electrochemical sensor. Heavy metals require careful monitoring …

Due to their toxicity to humans and animals, heavy metals and nitrate in groundwater are of
particular concern. The combination of high toxicity and widespread occurrence has created …

There is an increasing need to assess the harmful effects of heavy-metal-ion pollution on the
environment. The ability to detect and measure toxic contaminants on site using simple, cost …
