In the past Pb2+ has been used in many industries, including gasoline, piping, toys, paints, and more. The use of lead has led to a natural increase of lead concentration in the environment especially in air and water. According to the U.S. CDC “no level of lead in blood is considered safe.” Exposure to very low amounts of lead can cause several health complications including developmental and neurological disorders. Over the past several years an emphasis has been placed in developing systems that can detect lead at a very low concentration. A great deal of work has been accomplished in the development of Pb2+ sensors that can not only detect but also quantify the amount and in some cases in the presence of other metal ions. Herein, we describe current regulations, mode of exposure and recent development of sensing techniques.

“…Divalent lead (Pb 2+ ), which is another heavy-metal pollutant, was detected with an optical fiber reflectance sensor, based on the well-known probe 2,7-bis(2-arsenophenylazo)1,8-dihydroxy-naphthalene-3,6-disulfonate immobilized on ion-exchanger beads. The reflectance of red light at 665 nm served as the analytical signal, and the Pb 2+ ion was sensed up to 21 ppm levels with an LOD of 0.01 ppm.…”

“…Various instrumentation based methods, such as X-ray absorption spectroscopy (XAS), inductively coupled plasmaoptical emission spectroscopy (ICP-OES), anodic stripping voltammetry (ASV), chromatography, atomic absorption spectrometry (AAS), inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), cold vapor AAS or flame AAS-ETA (electrothermal atomization) and photometry are used for Pb 2+ determination at ppm and ppb levels in various matrices [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Although these conventional methodologies are accurate, but are allied with tedious sample pre-treatment, sophistication, time consumption, expertise, and usually lack convenience for routine analysis of bulk of samples.…”

Substantial utility of lead in numerous industries (storage, batteries, gasoline, cable manufacture, paint and ammunition), has resulted in recurring of environmental contamination. Lead being one of the highly abundant elements in nature, ranks third among the list of toxic substances. Owing to its ever-increasing demand and allied toxicity (memory loss, irritability, anemia, muscle paralysis, and mental retardation), development of novel synthetic receptors suitable to track Pb 2+ in vitro as well as in vivo has been an exciting area of research in the past few decades. In this review, emphasis has been diverted to summarize and briefly discuss major contributions made towards development of fluorescent abiotic receptors capable of sensing ionic lead (Pb 2+ ) under aqueous environments as well as in living cells.
