“…Land pollution will directly lead to the deterioration of soil properties in terms of eco-environmental effects, resulting in the reduction of vegetation and biodiversity. In addition, land pollution may also cause secondary environmental problems such as threatening ecological security and air and water pollution [31,34]. In addressing the issue of environmental pollution, comprehensive integrated control can be achieved by combining pollution abatement and environmental monitoring [35,36].…”

Electrospun nanofibers have shown their advantages for applications in a wide variety of scientific fields thanks to their unique properties. Meanwhile, electrospinning is closely following the fast development of nano science and nanotechnology to move forward to smaller (pico-technology), more complicated nanostructures/nanodevices and more order (all kinds of nano arrays). Particularly, multiple-fluid electrospinning has the strong capability of creating nanostructures from a structural spinneret in a single-step and a straightforward “top-down” manner, holding great promise for creation on a large scale. This review is just to conclude the state-of-art studies on the related topics and also point out that the future directions of environmental detection require chemosensors, while the improvement of sensors requires new chemically synthesized functional substances, new nanostructured materials, application convenience, and functional integration or synergy. Based on the developments of electrospinning, more and more possibilities can be drawn out for detecting environmental pollutants with electrospun nanostructures as the strong support platform.

“…For example, in one of our earlier works, we have proposed a microscopic sphere based optical fiber sensor for copper ion detection. 12 Coating a fiber optic surface with a thin layer of gold, silver, copper, and aluminium may give rise to the oscillation at the metal-dielectric interface known as SPR. 13 With the advent of photonic crystal fiber (PCF), most of the limitations of conventional SPR-based optical sensors are removed.…”

.To monitor the health of agricultural soil, lead (Pb2 + ) ion measurement is essential. The various sensors for lead ion detection reported in the literature earlier are either expensive or have complicated designs. This inspired us to propose a fiber optic sensor that is simple in design, less expensive, and more efficient. A photonic crystal fiber (PCF)-unclad single mode fiber (SMF)-PCF hybrid configuration makes up the suggested sensor, and the sensing mechanism is based on a synergistic application of surface plasmon resonance and interferometry. It is shown that the suggested structure is easy to use for Pb2 + ion detection, in addition to other advantages in limit of detection (LOD) and sensitivity. The proposed structure is optimized to attain a LOD of 8.32 mg / kg, which is much less than the permissible limit of Pb2 + ions permitted in healthy agricultural soil, i.e., 100 to 400 mg / kg. Additionally, a polymer that is attached atop the gold layer and to which only Pb2 + ions can adhere ensures the sensor’s specificity. To the best of our knowledge, our proposed optical fiber-based sensor design and approach adopted to detect lead ions in agricultural soil are the first of their kind.
