Waiter, Is There a Fungicide in My Soup?

The science of biomonitoring continues to develop new technologies to inform governments, industry and individuals about what chemicals get into the environment - and into us - that shouldn't be there.
Most of these monitoring techniques are expensive and complicated, and can take hours or days to produce results. I know, because I have had labs test me for detectable levels of hundreds of chemical toxins--pesticides, metals, flame retardants, and more--for a story published in 2006.,
Now a team of chemists at McMaster University in Ontario have published a paper in Analytical Chemistry that describes a new biomonitoring technique using treated paper on a stick that can quickly identify trace amounts of pesticides in your chicken soup, or your first early morning cup of joe.
As reported in R&D:
The scientists describe the development of a new paper-based test strip that changes color shades depending on the amount of pesticide present. In laboratory studies using food and beverage samples intentionally contaminated with common pesticides, the test strips accurately identified minute amounts of pesticides. The test strips, which produced results in less than 5 minutes, could be particularly useful in developing countries or remote areas that may lack access to expensive testing equipment and electricity, they note.

Picoyoctosensitive Food Testing
New sensitivity for food testing is at the forefront of research relevance. The recent advances of AFM/SEM imaging give only optical data without the essential electron, wave, photon, and energy and force field topological images necessary for learning the quantum-relativistic factors of specific molecules. That all relies on the atomic topological function used to analyze molecular quantum mechanics, the door to fast, powerful chemical laboratory analytical techniques.
Recent advancements in quantum science have produced the picoyoctometric, 3D, interactive video atomic model imaging function, in terms of chronons and spacons for exact, quantized, relativistic animation. This format returns clear numerical data for a full spectrum of variables. The atom's RQT (relative quantum topological) data point imaging function is built by combination of the relativistic Einstein-Lorenz transform functions for time, mass, and energy with the workon quantized electromagnetic wave equations for frequency and wavelength.
The atom labeled psi (Z) pulsates at the frequency {Nhu=e/h} by cycles of {e=m(c^2)} transformation of nuclear surface mass to forcons with joule values, followed by nuclear force absorption. This radiation process is limited only by spacetime boundaries of {Gravity-Time}, where gravity is the force binding space to psi, forming the GT integral atomic wavefunction. The expression is defined as the series expansion differential of nuclear output rates with quantum symmetry numbers assigned along the progression to give topology to the solutions.
Next, the correlation function for the manifold of internal heat capacity energy particle 3D functions is extracted by rearranging the total internal momentum function to the photon gain rule and integrating it for GT limits. This produces a series of 26 topological waveparticle functions of the five classes; {+Positron, Workon, Thermon, -Electromagneton, Magnemedon}, each the 3D data image of a type of energy intermedon of the 5/2 kT J internal energy cloud, accounting for all of them.
Those 26 energy data values intersect the sizes of the fundamental physical constants: h, h-bar, delta, nuclear magneton, beta magneton, k (series). They quantize atomic dynamics by acting as fulcrum particles. The result is the picoyoctometric, 3D, interactive video atomic model data point imaging function, responsive to keyboard input of virtual photon gain events by relativistic, quantized shifts of electron, force, and energy field states and positions.
Images of the h-bar magnetic energy waveparticle of ~175 picoyoctometers are available online at http://www.symmecon.com with the complete RQT atomic modeling manual titled The Crystalon Door, copyright TXu1-266-788. TCD conforms to the unopposed motion of disclosure in U.S. District (NM) Court of 04/02/2001 titled The Solution to the Equation of Schrodinger.
